Delta Sound Labs Stream Pro

Infinite Textures From Any Audio

Stream Pro is a complete granular synthesis platform: evolving textures, playable polyphonic instruments, and immersive 3D spatial audio - all in one plugin.

Granular synthesis breaks audio into grains of 1-100 ms and reassembles them: time-stretch without changing pitch, pitch-shift without changing time, and turn any recording into something entirely new.

Single Mode - Turn Any Sound into Evolving Textures

• Record, Overdub, and Replace capture modes
• Independent pitch and time control
• Bipolar speed & direction (-2x to +2x) with freeze
• One-tap buffer undo - recording over a take is no longer fatal
• Session persistence: your buffer and settings restore automatically

Multi Mode - Play Your Samples Like an Instrument

• Full polyphonic MIDI tracking - up to 8 voices
• Per-voice ADSR envelopes with a draggable visual editor
• Colored voice markers show every playhead at a glance
• Genuinely stochastic per-grain jitter
• Efficient Stroma engine keeps polyphony light on CPU

3D Spatial Granular Synthesis

Powered by Steam Audio's binaural HRTF processing, the Spatializer places each voice in true 3D space for headphone listening - or scatters grains across the stereo field in classic ping-pong style.

• Binaural HRTF processing - drag voice nodes on the XY pad; in Multi mode, every note occupies its own position in the soundstage.
• Ping-pong grain distribution - successive grains alternate hard-left and hard-right, with a pulse rate that tracks grain size.
• BOIDS flocking - voice nodes cluster, burst apart, and regather in ever-changing spatial patterns, no manual animation required.
• Motion & DAW automation - record and loop per-voice movement paths, and automate spatial position and the binaural-to-ping-pong blend from your DAW.
